JNO. L. BASSETT, OF BRIDGEPORT, CONNEC'IIGU'I.4

WIDOW-BLIND FASTENER.

Specification of Letters Patent No. 5,305-, dated September 2,5, 1847.

To all 'wh-0m t may concern Be it known that I, JOHN L. BASSETT, ofBridgeport, in the county of Fairfield and State of Connecticut, haveinvented a new and useful Improvement on Window-Blind Shutters andDoor-Fastenings; and do here-y by declare thatV the following is a full,clear, and exact description of the construction andV operation of thesame, reference being had to the annexed drawings, making a part of thisspecification, in which.d t

Figure 1, 1s a perspective view of the latch piece disconnected from theplate and spring. Fig. 2 is also a perspective view ofv the latch pieceplate and spring connected, the latch piece having been slipped into themortise of the plate and the spring put around the prong. Fig. 4represents the fastening turned upside down. Fig. 6 repsesents the blindfastening plate.` Fig. 3`

represents the spiral spring.

The nature of my improvement consists in providing a latch for a blindor shutter or door fastening with certain parts which connect it to theplate. One ofsaid parts is set 0H on the edge or side of the latch whichI name a shoulder F. This sets on the plate. Another 2d one of theseparts is a projecting branch A, setting out some distance onthe otheredge of the latch and rests on the plate. Another 3d one of said partsis a narrow strip. I name it prong B, which is plate is D, the pointranging with the edge of the plate. I call it notch. The center of thenotch D sets against the edge of first mentioned makes one'side ofsaidnotch.

Theother side of the notch is made 'by a jut called E.

To enable others skilledin the art to make lthe plate. They under partof they shoulder and use my improvement, I will proceed to describe itsconstruction and operation. *n

I construct my appendages to hold back against and to the building inany of the known forms; also the hook part on the ends of the latchpattern are shaped like any of' the known forms. VButpin orderto obviatethe expense and labor` arising from boring vout from the plate byriveting on the sides of the mortise projecting pieces for holding apivot for t-he latch to swing on, I make a notch in the edge of thelatch piece so that it rests immediately on the plate as shown at l F inthe accompanying drawing.

I in general cast the latch piece of brass 'or iron, first having made acorrect pattern.

I construct a sufficient number in imitation of it and arrange them on aplate of metal'or a board in rows in a manner most convenient formolding. They maybe cast'out of any of themetals generally used for sucharticles or if more convenient they may be stamped out with a die andplate.

What I claim as my improvement and desire to secure by Letters Patentis- Connecting the latch to the plate by the notch D and projectingbranch A in combination with the prong B and spring 3;

Witness my' hand this fteenth day of` September 1847.
